ext4online

ext4online is a utility used in the Linux operating system that allows users to resize ext4 file systems while they are mounted and actively in use. This means you can increase the storage space of a partition without needing to shut down or unmount it, minimizing disruptions. It makes managing disk space more efficient, especially in environments where uptime is crucial. However, it is primarily designed only for enlarging file systems, not for shrinking them. Overall, ext4online helps users adapt their storage needs on the fly, ensuring better resource allocation and performance.
